Diagnostic miRNA profiles in multiple sclerosis
The invention relates to methods for diagnosing multiple sclerosis with miRNA markers. Diagnosis of multiple sclerosis (MS) can be challenging in patients with atypical presentations and during a first neurological deficit possibly related to inflammatory demyelination. Towards the identification of biomarkers for diagnosis of MS, a comprehensive analysis of miRNA expression patterns was obtained. Significantly deregulated miRNAs were identified, which have previously not been related to MS according to the microRNA disease database. These miRNAs could potentially serve as future diagnostic biomarkers for MS and help in diagnosis, monitoring disease activity, and evaluation of treatment responses in patients with MS.
1. A method for treating relapsing and remitting multiple sclerosis (RRMS) in a patient in need thereof at the clinical isolated syndrome (CIS) stage of RRMS, said method comprising:
administering an immunomodulatory or immunosuppressive therapy to the CIS stage patient, wherein a sample taken from the patient before administration of the therapy is measured by next generation sequencing and exhibits:
more than 6 read counts for hsa-miR-22-5p;
more than 4.806 read counts for hsa-miR-125b-5p;
more than 4.847 read counts for hsa-miR-629-5p;
more than 418.792 read counts for hsa-miR-16-2-3p;
more than 3.993 read counts for hsa-miR-100-5p;
fewer than 7.194 read counts for hsa-miR-20a-5p;
fewer than 580.403 read counts for hsa-miR-151a-3p; or
fewer than 2.681 read counts for hsa-miR-7-1-3p.
